Product details

Overview

74LVC02AD/C4J from Nexperia is a quad 2-input NOR gate logic IC operating at 1.65–3.6 V supply, with typical propagation delay of 3.1 ns at 3.3 V and output drive capability of ±24 mA. It performs basic Boolean NOR logic in digital control paths, commonly used in address decoding and enable signal generation for memory subsystems.

For engineers reviewing the 74LVC02AD/C4J datasheet, 74LVC02AD/C4J pinout, 74LVC02AD/C4J application, or 74LVC02AD/C4J equivalent, key selection criteria include supply voltage range, output drive strength, propagation delay consistency across channels, and guaranteed operation down to 1.65 V for mixed-voltage interface designs.

Technical Context

This device belongs to the 74LVC family of low-voltage CMOS logic, designed for interoperability between 3.3 V and 2.5 V systems. All four NOR gates share identical electrical characteristics, including matched input thresholds (V_IH = 2.0 V min, V_IL = 0.7 V max at V_CC = 3.3 V) and rail-to-rail output swing.

It features ESD protection exceeding 4 kV HBM and operates over the industrial temperature range (−40 °C to +125 °C), supporting reliable use in automotive body control modules and industrial PLC I/O expansion cards without external level-shifting circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input NOR gate - enables independent OR-inverted logic per channel for discrete control signal conditioning
Supply Voltage Range	1.65 V to 3.6 V - supports direct interfacing with both 2.5 V and 3.3 V microcontrollers and FPGAs
Propagation Delay	3.1 ns typical at V_CC = 3.3 V - ensures timing predictability in synchronous enable/decode paths up to 100 MHz
Output Drive	±24 mA at V_CC = 3.3 V - drives standard TTL loads or multiple 74LVC inputs without fanout limitation
Input Thresholds	V_IL ≤ 0.7 V, V_IH ≥ 2.0 V at V_CC = 3.3 V - guarantees noise margin > 0.6 V in noisy industrial environments
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive and factory-floor industrial applications

Pinout & Package

74LVC02AD/C4J is housed in a 14-pin SO14 (Small Outline) package with 1.27 mm pitch, JEDEC MS-012AC compliant, and rated for surface-mount reflow assembly.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	Input A/B per gate	Dedicated logic inputs for each of four NOR gates - no shared inputs; fully independent channel operation
3, 6, 10, 13	Output Y per gate	Push-pull CMOS outputs - no open-drain configuration; compatible with standard logic loads
7	GND	Ground reference for all logic and output stages - must be connected to system ground plane
14	V_CC	Single positive supply input - powers all four gates; no separate V_CC per channel

Key Features

Feature	Design Value
Overvoltage tolerant inputs	Inputs withstand up to 5.5 V regardless of V_CC, enabling safe connection to legacy 5 V buses
Dynamic power control	Typical I_CC = 10 µA at 1 MHz - reduces quiescent current in battery-backed control logic
Monotonic output transition	No output glitches during supply ramp-up/down - prevents false triggering in power sequencing circuits
IOFF partial power-down	Outputs go high-impedance when V_CC = 0 V - allows live insertion into powered backplanes

Applications

Memory Address Decoding

Industrial I/O Enable Logic

Use Scenario: Generating chip-select signals for SRAM and flash memory banks in microcontroller-based data loggers.

IC Role / Device Role / Timing Role: NOR gate implements active-low decode logic combining address bits to assert /CS only when target memory region is accessed.

Use Value: Propagation delay <3.5 ns ensures setup/hold timing margins are maintained at 20 MHz bus clock rates.

Use Scenario: Enabling/disabling analog sensor input channels in programmable logic controller (PLC) modules.

IC Role / Device Role / Timing Role: Gate output controls analog multiplexer enable pin, synchronizing channel selection with digital control state.

Use Value: ±24 mA drive strength directly switches multiplexer control inputs without buffer amplification.

Automotive Body Control

USB Hub Power Management

Use Scenario: Combining door lock/unlock request signals with ignition status to gate window motor activation.

IC Role / Device Role / Timing Role: NOR gate acts as safety interlock - output asserts only when both conditions are inactive (fail-safe default).

Use Value: −40 °C to +125 °C rating ensures uninterrupted operation in engine bay-mounted control units.

Use Scenario: Controlling VBUS power delivery to downstream USB ports based on host enumeration status and overcurrent detection.

IC Role / Device Role / Timing Role: NOR output drives high-side load switch gate, turning off port power when fault or suspend condition occurs.

Use Value: Overvoltage-tolerant inputs accept 5 V USB status signals while powered from 3.3 V system rail.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR gate logic applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC02APW	Same logic function and electrical specs; TSSOP-14 package with 0.65 mm pitch	Higher board density possible but requires finer-pitch reflow profile	Select when PCB layout prioritizes space over assembly compatibility
74AHC02D	Wider V_CC range (2–5.5 V); higher propagation delay (7.5 ns typ)	Better suited for 5 V legacy systems; less suitable for high-speed 3.3 V interfaces	Select when interfacing with 5 V peripherals and speed <50 MHz is acceptable

Compared with SN74LVC02APW and 74AHC02D, the 74LVC02AD/C4J offers optimal balance of speed, low-voltage operation, and SO14 manufacturability - making it preferred for new 3.3 V industrial and automotive designs requiring proven assembly yield.

FAQ

What is the maximum clock frequency supported by 74LVC02AD/C4J?

The 74LVC02AD/C4J is not a clocked device and has no defined clock frequency. Its usable toggle rate depends on propagation delay and system loading. With 3.1 ns typical t_PD, it supports clean signal transitions up to approximately 100 MHz in lightly loaded point-to-point configurations, assuming proper PCB layout and termination.

Can 74LVC02AD/C4J be used with a 5 V microcontroller?

Yes - its inputs are overvoltage tolerant up to 5.5 V, allowing direct connection to 5 V GPIO outputs. However, outputs swing only to V_CC (max 3.6 V), so interfacing with 5 V logic inputs requires a pull-up resistor or level translator unless the receiving device accepts 3.3 V logic-high levels.

Does 74LVC02AD/C4J support hot-swap or live-insertion?

Yes - it features IOFF circuitry that forces outputs into high-impedance when V_CC = 0 V. This prevents back-powering or signal contention during live insertion into powered backplanes or hot-pluggable modules, provided inputs remain within absolute maximum ratings.

Is there a lead-free and RoHS-compliant version of this part?

Yes - the /C4J suffix denotes a lead-free, halogen-free, RoHS-compliant variant in a matte-tin plated SO14 package. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and is qualified for lead-free reflow soldering per IPC/JEDEC J-STD-020.
